We used to adore Addie's and Black's Bar and Kitchen. The latter started to lose it about a year ago - I had a dish that simply didn't work. The ingredients didn't work together at all.
We have a 3-strikes rule. We figure one bad meal can be a fluke, an off-night, a bad dish on an otherwise solid menu. Second time, the restaurant is definitely slipping, and third time, it is off our list.
We never got to three strikes with Black's because we struck the entire Black's empire off our list when they refused to give us reservations at the place in Garrett Park so my handicapped mother wouldn't have to stand and wait for a table. They were absolutely inflexible about it, claiming that if we drove up right away there would be no wait. We live 10 minutes from Garrett Park and it was just before 6 p.m. (earlier than we wanted to eat, but...) so we ran up there - and every table was occupied. There were two places to sit at wait - at the extremely cramped little bar, which sits directly between the kitchen and the tables, so the waitstaff was squeezing by every few seconds, or a rickety chair out in the cold, empty hallway.
I don't miss them (or the overly-warm wine they served at Black's, because they didn't have proper storage...). I also don't miss their arrogant attitude towards customer preference. They have a good burger, but refuse to give you steak sauce - I hate catsup. The waitstaff were very apologetic about the chef's inflexible insistence that people eat his food his way (must have interned with Carole Greenwood).
Though I did enjoy the occasional meltdown in the kitchen (chef screaming at the top of his lungs). We called it the "Floor Show."
